the vehicle-frame.

. out in the claims.

Figure l is a side elevation showing my improved fork and fork-stemconnection. Fig. 2 is a plan view, and Fig. 3 a front view, of the same.Figs. 4 and 5 indicate a modification embodying the main features of myinvention.

The fork-stem 1, which is fitted to the forward portion of the frame, asusual, is provided at its lower end, as shown, with a fork connectingfitting 2, forming a T-shaped end with a rearwardlyextending pivot-arm 3and a forwardlyextending cushion-arm 4;. The fork comprises the usualfork sides 5 5 and a uniting crown portion 6, which, as shown, isspecially formed and shaped for connection to the fork-stem fitting 2,as follows: The crown 6 is a U-shaped connection for the fork sides 5 5,arranged fiatwise upon the latter with the bend 7 thereof extendingforward of the points of junction with the fork sides and its spreadends 8 8 forming a pivoting-j aw for connection to the pivot-arm 3 ofthe fork-stem end fitting 2 by means of a horizontal pivot-bolt 9, uponwhich the fork is adapted to swing a limited distance forward orbackward. This swinging movement is controlled by a vertical springconnection between the forwardlyextending portion of the fork-stemfitting 2 and of the crown 6, the bend 7 of the latter, as shown, beingarranged to overlie the cushioning-arm 4 of the fitting 2 and beingyieldingly connected to the latter by means of a vertical bolt or bolts10, upon which are strung spiral springs 11 and 12, arranged to press inopposite directions upon the pivoted fork-crown, together withadjusting-nuts 13 for varying the tension, of said springs and acasing-cup ,14. and cap 15. The effect of said springs,

for a vertical cushioning movement of the connected forward portions ofthe fitting 2 and crown 6 about the pivot-bolt 9, which movement is, asusual, readily regulated for varying requirements to the extentof'making the connection approximately rigid by tightly drawing up thespring-adjusting nuts.

The preferred construction which has been thus specifically describedmay be modified without departing from the main features of myinventionfor instance, as indicated in Figs. 4 and 5, in which the crown6 is so shaped and arranged as to underlie the cushioning-arm of thefitting 2 instead of overlying the latter, as in the preferredconstruction and which is shown with a single spring connection insteadof two.

What I claim is 1. The combination with a fork-stem having a T-shapedfork-connecting end, of a fork having a U-shaped crown which is pivotedat its spread ends to one arm of said T-shaped end and the bend of whichoverlies the other arm thereof and has a spring connection to thelatter.

2. The combination with a fork-stem having a T-shaped fork-connectingend, of a fork having a U-shaped crown which is pivoted at its spreadends to one arm of said T-shaped end by means of a horizontalpivot-bolt, and the bend of which overlies the other arm thereof and isyieldingly connected to the latter by means of a vertical bolt havingreversely-acting springs thereon, means for adjusting the tension ofsaid springs, and a casing, substantially as set forth.

In testimony whereof I affix my signature in the presence of twowitnesses.
